Question on difference between bootloaders?

OK... thanks

I guess I wasnt using the correct terminology then.. :slight_smile:

what is the difference between the board profiles (better? Im not sure how else to describe it then?) form the boards menu in the Arduino IDE of Lilypad and Pro/Pro-Mini?.

or more Direct.. why/when choose the Lilypad board profile? What benefits? What specs/requirements do you need to use Lilypad? (+3.3v? 8Mhz? Internal? External?)

thanks!
